205AT CA HF$Using R0(205AT)=1.484 8, unweighted average deduced from
205AT2CA values for neighboring even-even 204PO (R0=1.476 6) and 206RN

209FR CP $1974Ho27: Mass separated source produced at the ISOLDE facility using
209FR2CP 600 MEV, 50 nA proton beam incident on a target containing an alloy of
209FR3CP La and Th. Detectors: silicon surface barrier detector with typical
209FR4CP energy resolution of 20 KEV. Measured: EA, IA, T1/2, %A. The energy
209FR5CP calibration was performed using a mass-separated 228TH source and
209FR6CP 239PU, 241AM and 244CM combination source.
